The invention discloses a method for prompting rapid
recovery of
vegetation in a bare sandy land and a blowout pit by combining a thoroughly decomposed sheep
manure biological crust with biological measures. The technology is mainly composed of techniques such as selection of suitable grass seeds and shrubs,
shrub cultivation, direct seeding of grass seeds and pavement of thoroughly decomposed sheep
manure. The method comprises the steps of: firstly, selecting types of grass seeds and shrubs suitable to be grown in highly cold desert regions, and then cultivating suitable shrubs in the bare sandy land and the blowout pit; secondly,
sowing the suitable grass seeds; finally paving the thoroughly decomposed sheep
manure on the surface of the
quicksand. After a period of time, the thoroughly decomposed sheep manure biological crust is formed on the surface of the
quicksand; the suitable
plant seeds and the sheep manure form a tightly combined and mutually depended integral body; the thoroughly decomposed sheep manure provides
nutrition to the growth of the suitable
plant seeds, has heat preservation,
moisture keeping and the like functions, can promote rapid growth of the
vegetation, provides a steady growth environment, avoids flow of the
quicksand and wind
corrosion, and is more conductive to the
recovery of the desert
grassland. The method for preventing and fixing sands by using sheep manure has the advantages of fast sand fixation speed, low cost, low labor cost, long storage time, rapid and convenient construction, easy operation, no
adverse effect for the environment and plants, and the like.
